Description

Technical Field

[0001] The present invention relates to the field of atomization technology, and in particular to a heated atomization core and an electronic atomization device thereof. Background Art

[0002] Electric heating atomization technology is a new type of atomization technology that has emerged in recent years. Its principle is to generate heat energy through the thermal effect of resistors, and the heat energy then heats the liquid and atomizes it into atomized steam. It is now widely used in medical, smart home appliances, and consumer electronics products. The atomization components currently used in the e-cigarette industry are mainly divided into soft liquid-conducting materials such as liquid-conducting cotton and hard liquid-conducting materials such as porous ceramics according to their liquid-conducting media. Among them, liquid-conducting cotton is widely used in the atomization industry because of its softer liquid-conducting material, high porosity, good liquid-conducting performance, and high taste restoration.

[0003] However, the current electronic atomization device with liquid-conducting cotton has the following defects: when the area of ​​the liquid-conducting cotton is large, the surrounding parts are pressed tightly, while the middle part is not pressed and bulged, which will cause the liquid-conducting gaps in the compressed surrounding parts to be smaller, while the middle part that is not pressed and limited will bulge and have a larger gap, which can easily cause the liquid-conducting gaps of various parts of the liquid-conducting cotton to be inconsistent. If the gap is too large, the liquid-locking ability of the liquid-conducting cotton will be reduced, and the atomized liquid will easily leak and drip due to its own influence. When the liquid-conducting cotton atomization core is used in conjunction with a flat heating element, because it is relatively soft and elastic, the different pressure conditions of each part during use will cause the gaps in the liquid-conducting cotton to be different in size, and oil leakage will occur. In addition, the temperature of the heating element is relatively high, and the core is very likely to become sticky during continuous use. Summary of the invention

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0034] When a component is referred to as being “fixed to” or “disposed on” another component, it may be directly or indirectly located on the other component. When a component is referred to as being “connected to” another component, it may be directly or indirectly connected to the other component.

[0035] The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution. The terms "first", "second", etc. are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0036] In the present invention, the horizontal direction refers to the direction of the line connecting the two liquid inlets of the upper cover, and the vertical direction refers to the direction perpendicular to the line connecting the two liquid inlets.

[0037] Embodiment 1, as Figure 1-Figure 21As shown, a heating atomizing core includes an upper cover 10 and a base 50, and liquid-conducting cotton 30 and a heating body 40 are arranged between the upper cover 10 and the base 50 in sequence. The upper cover 10 is provided with a cotton pressing piece 20 for pressing the liquid-conducting cotton 30, or a cotton pressing piece 20 is provided between the upper cover 10 and the liquid-conducting cotton 30, and the cotton pressing piece 20 at least includes at least one pressure strip 21 for pressing the top surface of the liquid-conducting cotton 30, and the pressure surface of the pressure strip 21 and the liquid-conducting cotton 30 forms a plane structure. The base 50 of the present invention is provided with an airflow inlet hole 51, and the cotton pressing piece 20 is provided with a liquid inlet channel 201 connected to the liquid inlet 111. By providing the cotton pressing piece 20, the pressure strip 21 is arranged on the cotton pressing piece 20, so that the pressure strip 21 presses the liquid-conducting cotton 30. Since the pressure surface of the pressure strip 21 forms a plane structure, the pressure surface of the pressure strip 21 described in the present invention forms a plane structure, which means that the bottom surface of the pressure strip 21 is on one plane, or the bottom surfaces of multiple pressure strips 21 are all on one plane. The pressure strip 21 presses the liquid inlet surface, i.e., the top surface, of the liquid-conducting cotton 30 to form a planar structure, thereby preventing the liquid-conducting cotton 30 from being deformed due to uneven force only on all sides. The liquid-conducting cotton 30 is evenly stressed, and the liquid-conducting gaps are of uniform size. The liquid-conducting cotton 30 has a good liquid-locking ability, thereby preventing the atomized liquid from leaking and dripping due to the enlargement of the liquid-conducting gap of the liquid-conducting cotton 30, and is less likely to become sticky, thereby optimizing the atomization effect and improving the atomization taste. When the heated atomizing core is working, the atomized liquid enters the liquid inlet channel connected to the liquid inlet from the upper cover 10, and the air enters from the airflow inlet hole 51 of the base 50. The atomized liquid enters the liquid-conducting cotton 30 through the cotton pressing piece 20, and the heating body 40 generates heat to generate heat, thereby atomizing the atomized liquid in the liquid-conducting cotton 30 to form atomized steam, and the atomized steam is mixed with the incoming air to form an aerosol, which is finally inhaled by the user.

[0038] The upper cover 10 and the base 50 are matched with each other, and are mainly used to accommodate the liquid-conducting cotton 30 and the heating body 40. The external forms of the two are not limited. The upper cover 10 includes a cover body 11 and a receiving portion 12 that can accommodate the liquid-conducting cotton 30. The receiving portion 12 is provided with an inner cavity 121 for cooperating with the base 50 to accommodate the liquid-conducting cotton 30 and the heating body 40. The cotton pressing piece 20 is arranged on the cover body 11 or in the inner cavity 121 of the receiving portion 12 close to the cover body 11, that is, the cotton pressing piece 20 and the upper cover 10 can be separate structures, and they are modeled separately during production, which is simpler to model. In this structure, the cotton pressing piece 20 is constrained by the upper cover 10 or pressed on the liquid-conducting cotton 30 by the upper cover 10. The shape of the cotton pressing piece 20 matches the inner cavity 121 of the receiving portion 12 of the upper cover 10 and / or the top of the liquid-conducting cotton 30. The cotton pressing piece 20 is placed in the inner cavity 121 of the receiving portion 12, and is located between the cover body 11 and the top of the liquid-conducting cotton 30. The upper cover 10 and the base 50 are tightly matched, plugged or snap-fitted to form a whole.

[0039] In addition, the cotton pressing piece 20 and the upper cover 10 can also be connected together, and the two can be detachably connected or fixedly connected, wherein the cover body 11 of the detachably connected upper cover 10 is a frame structure, and the cotton pressing piece is screwed, snapped, pinned, or tightly fitted in the cover body 11. The fixed connection method can be that the cotton pressing piece 20 is fixed on the wall surface of the cover body 11. Furthermore, the cotton pressing piece 20 and the upper cover 10 can also be an integrated structure, and the cotton pressing piece 20 is located in the inner cavity of the accommodating portion 12. This structure does not require multiple modeling during production, but only needs to be modeled once, and the assembly step is also omitted.

[0040] There are many implementation methods for the structure and appearance of the cotton pressing member 20: the cotton pressing member 20 can be a relatively thin flat structure, made of metal with a certain strength; Figure 3 As shown, the cotton pressing member 20 may also be a three-dimensional structure with a certain thickness and strength, and the manufacturing material is not specifically limited.

[0041] The main structure of the cotton pressing piece 20 includes a pressure strip 21. The number of pressure strips 21 can be one or more. When one is set, the pressure strip 21 preferably passes through the center or near the center of the top surface of the liquid-conducting cotton 30. When multiple are set, at least one pressure strip 21 preferably passes through the center or near the top surface of the liquid-conducting cotton 30. In this way, both the edge and the center of the top surface of the liquid-conducting cotton 30 can be pressed. When one pressure strip is set, the pressure strip can be selected to be wider, or a branch can be extended outward at any position on the pressure strip 21 to expand the pressure area of ​​the pressure strip 21. Preferably, branches are provided at both ends of the pressure strip 21. Similarly, when multiple pressure strips 21 are set, branches can also be provided on the pressure strip 21. However, the cotton pressing piece 20 or the pressure strip 21 cannot cover the entire top surface of the liquid-conducting cotton 30 or block the liquid inlet 111. The cotton pressing piece 20 needs to have a liquid inlet channel 201 connected to the liquid inlet 111. In order to achieve better pressing, it is preferred to provide a plurality of pressure strips 21 , and the plurality of pressure strips 21 can be evenly distributed on the top surface of the liquid-conducting cotton 30 to evenly press the liquid-conducting cotton 30 .

[0042] The shape of the bead 21 has many embodiments: the cross section of the bead 21 is polygonal, curved, or a combination thereof, that is, the shape of the bead 21 can be a cuboid, a cylinder, a polyhedron, or a combination of a cylindrical bead 21 and a cuboid bead 21, or a combination of a cylindrical bead 21 and a polyhedron bead 21, or a combination of a cuboid bead 21 and a polyhedron bead 21. The shape of the bead 21 is not specifically limited. Figure 4-11 The diameter or width of the bead 21 shown can be the same, that is, bead of equal diameter, such as Fig.12 The diameter or width of the pressure strip 21 shown can be different. It is a pressure strip with a variable diameter. The diameter can be changed at any position and can be gradually increased or decreased. It can also be changed arbitrarily, and the present invention is not limited to this.

[0043] There are many ways to implement the direction of the pressure strip 21: Figure 4-Figure 17 As shown, the bead 21 can be at least one of a transverse bead 211, a vertical bead 212 or an oblique bead 213. Since the upper cover 10 is provided with at least one liquid inlet 111 for the atomized liquid to enter, the liquid inlet 111 passes through the top surface of the upper cover 10 and enters the inner cavity 121 of the accommodating portion 12. Preferably, two liquid inlets 111 are correspondingly arranged on both sides of the upper cover 10, and the atomized liquid enters from the liquid inlets 111 on both sides of the upper cover 10 and is poured into the top surface of the liquid-conducting cotton 30. The atomized liquid entering the inner cavity 121 converges to the middle in the horizontal direction, so the direction of the bead 21 affects the flow rate of the atomized liquid. The transverse bead 211 and the oblique bead 213 can enable the atomized liquid to smoothly reach various positions of the liquid-conducting cotton 30 in the horizontal direction, and the vertical bead 212 will slow down the flow rate of the atomized liquid in the length direction, so it is preferred to set more transverse bead 211 and oblique bead 213. The pressure strip 21 is provided to press the liquid-conducting cotton 30 to form a planar structure, that is, to make the liquid inlet surface (top surface) of the liquid-conducting cotton 30 form a planar structure. In this way, after the liquid-conducting cotton 30 is pressed, the gaps between the various parts are smaller, and there will be no large difference in tightness, so that the liquid-conducting cotton 30 has better liquid conduction consistency.

[0044] The transverse bead 211, the vertical bead 212, and the oblique bead 213 can be independently arranged or in any combination. For example, the transverse bead 211 is combined with the vertical bead 212, the vertical bead 212 is combined with the oblique bead 213, the transverse bead 211 is combined with the oblique bead 213, or the transverse bead 211, the vertical bead 212, and the oblique bead 213 are combined.

[0045] There are many ways to arrange the layer strips 21, such as Figure 4-Figure 17 As shown, the transverse pressure strips 211, the vertical pressure strips 212 and the oblique pressure strips 213 are arranged in a straight line, a curve or a combination thereof. The multiple pressure strips 21 are arranged in a regular order and symmetrically, or they can be arranged randomly. The curve refers to any curve, such as an arc, a parabola, a spiral and other arbitrary curve structures. The combination can be a plurality of straight lines connected to form a broken line structure, a straight line branch structure, etc., a wave shape, a curved branch structure, etc. formed by the combination of curves and curves, or a combination of straight lines and curves. The specific arrangement method is not limited; in a specific embodiment, the cotton pressing member 20 includes a vertical pressure strip 212 and a transverse pressure strip 211. The pressure strip 21 presses the liquid-conducting cotton 30 arranged below, so that a whole piece of liquid-conducting cotton 30 with a larger area is decomposed into 4 liquid-conducting cottons 30 with equal areas, so that the various parts of the liquid-conducting cotton 30 are compressed more uniformly, so that the liquid-conducting gaps of the liquid-conducting cotton 30 are of the same size, so that the liquid-conducting cotton 30 has a good liquid locking ability.

[0046] The pressure strip 21 is the basic structure of the cotton pressing member 20 of the present invention. On the basis of the above structure, a frame 22 can be provided around the pressure strip 21. The shape and position of the frame 22 are consistent with the shape of the top surface of the liquid-conducting cotton 30. Figure 4-Figure 6 As shown, the cotton pressing member 20 is a separate pressing strip 21 pressing against the liquid-conducting cotton 30. Figure 7-Figure 15 As shown, the cotton pressing member 20 includes a pressing strip 21 and a frame 22 arranged around the pressing strip 21 . The frame 22 and the pressing strip 21 are connected to form a whole for pressing the liquid-conducting cotton 30 .

[0047] like Figure 4 As shown, the cotton pressing member 20 includes two linear transverse pressing strips 211 and a vertical pressing strip 212, and the vertical pressing strip 212 corresponds to the center of the top surface of the liquid-conducting cotton 30. Figure 5 As shown, the cotton pressing member 20 includes two curved transverse pressing strips 211 and a straight vertical pressing strip 212, and the straight vertical pressing strip 212 corresponds to the center of the top surface of the liquid-conducting cotton 30. Figure 6 As shown, the cotton pressing member 20 includes two straight-line oblique pressing strips 213 , and the two oblique pressing strips 213 are arranged to cross each other, and the central intersection point of the straight-line oblique pressing strips 213 corresponds to the center of the top surface of the liquid-conducting cotton 30 .

[0048] like Figure 7 As shown, the cotton pressing member 20 includes two linear transverse pressing strips 211 and a frame 22. The two linear transverse pressing strips 211 correspond to the vicinity of the top center of the liquid-conducting cotton 30. Figure 8 As shown, the cotton pressing member 20 is Figure 4 A border 22 is added on the basis. Fig. 9 As shown, the cotton pressing member 20 is Figure 7 The two straight-line transverse beading strips 211 are changed into curved transverse beading strips 211. Fig.10 As shown, the cotton pressing member 20 includes three straight-line oblique pressing strips 213 and a frame 22, and the middle straight-line oblique pressing strip 213 corresponds to the center of the top surface of the liquid-conducting cotton 30. Fig.11 As shown, the cotton pressing member 20 is Figure 6 A border 22 is added on the basis. Fig.12 As shown, the cotton pressing member 20 is Figure 8 The two straight horizontal strips 211 of equal diameter are changed into horizontal strips 211 of non-equal diameter, and the diameter of the horizontal strips 211 gradually decreases toward the center. Fig.13 As shown, the cotton pressing member 20 includes four straight oblique pressing strips 213, a vertical pressing strip 212 and a frame 22. One end of the oblique pressing strip 213 is connected to the four corners of the frame, and the other end extends to the vicinity of the top center of the liquid-conducting cotton 30. The vertical pressing strip 212 passes through the top center of the liquid-conducting cotton 30. Fig.14As shown, the cotton pressing member 20 includes four straight-line oblique pressing strips 213 and a frame 22. One end of the oblique pressing strip 213 is connected to the four corners of the frame, and the other end extends to the vicinity of the center of the top surface of the liquid-conducting cotton 30. Fig.15 As shown, the cotton pressing member 20 is Fig. 9 A vertical pressure strip 212 is added on the basis, and the vertical pressure strip 212 passes through the center of the top surface of the liquid-conducting cotton 30. Fig.16 As shown, the cotton pressing member 20 includes a frame 22 and two curved transverse pressing strips 211. Fig.17 As shown, the cotton pressing member 20 is Fig.16 A vertical pressure strip 212 is added on the basis, and the vertical pressure strip 212 passes through the center of the top surface of the liquid-conducting cotton 30.

[0049] like Figure 18-Figure 21 As shown, on the basis of the above-mentioned heating atomization core, a porous ceramic piece 60 can also be provided between the liquid guiding cotton 30 and the heating body 40, and the bottom surface of the porous ceramic piece 60 is attached to the heating body 40; the liquid inlet end of the heating atomization core adopts a softer liquid guiding cotton 30 with high porosity and good liquid guiding performance as a liquid guiding medium, and the part in contact with the heating body 40 adopts the porous ceramic piece 60 as the liquid guiding medium. The liquid inlet end adopts the liquid guiding cotton 30 to improve the efficiency of liquid guiding and liquid locking, so that the liquid guiding cotton 30 of the heating atomization device can fill the gap between the parts when the oil supply is sufficient, and play a good role in locking oil and preventing seepage. The liquid guiding cotton 30 has the function of fast liquid guiding and liquid locking. Since the liquid guiding cotton 30 is soft, it can also fill Filling the gap between the porous ceramic part 60 and other parts of the heating atomization core can effectively seal and prevent liquid from leaking in the gap, so the silicone and silicone assembly process can be omitted; the porous ceramic part 60 is a high-temperature resistant, solid hard material liquid conductor, which can be used as a carrier of the strengthless heating body 40, which is equivalent to the entire flat surface of the porous ceramic part 60 being pressed on the liquid conductor cotton 30, so that the liquid conductor cotton 30 is evenly compressed, the liquid conduction is more uniform, the liquid conduction efficiency is optimized, and the heating body 40 is attached to the bottom surface of the porous ceramic part 60, so that the heating body 40 is in good contact with the liquid conductor, the heating body 40 is not easy to deform, and the porous ceramic part 60 is resistant to high temperatures and will not carbonize, and the service life is greatly improved.

[0050] The heating body 40 is generally made of stainless steel, nickel-chromium, iron-chromium-aluminum, nickel-iron and other alloys with high resistivity, and the thickness can be between 0.03-0.2mm. The specific thickness is not limited. The heating body 40 can be made of metal sheets through a corrosion cutting process to form a heating track embedded in the bottom surface of the porous ceramic part 60, or the heating track can be printed on the bottom surface of the porous ceramic part 60 through thick film printing. The porous ceramic part 60 is a thin sheet structure, such as a thickness between 0.1-2mm. The purpose of the thinner design is to prevent the porous network structure of the porous ceramic part 60 from blocking the permeability of large molecules in the smoke oil. The porous ceramic part 60 is only used for its good strength, high temperature resistance, not easy to carbonize, and can support and fix the heating body 40, thereby avoiding the occurrence of poor contact with the heating body 40.

[0051] The shape of the top surface of the porous ceramic part 60 is consistent with the shape of the bottom surface of the liquid-conducting cotton 30, which can make the bottom surface of the liquid-conducting cotton 30 abut more closely against the porous ceramic part 60, so that the gap difference between each part is smaller after the liquid-conducting cotton 30 is pressed, and there will be no large difference in tightness, so that the liquid conduction consistency from the liquid-conducting cotton 30 to the porous ceramic part 60 is better; the shape of the bottom surface of the porous ceramic part 60 is matched with the shape of the heating circuit of the heating body 40, so that the two are tightly fitted, avoiding the poor contact between the porous ceramic part 60 and the heating body 40, so that the heat generated by the heating circuit of the heating body 40 is used to heat the atomized liquid on the porous ceramic part 60 to the maximum extent, optimize the atomization effect, and improve the atomization taste.

[0052] The porous ceramic member 60 is provided with at least one of a liquid conducting hole, a liquid conducting groove 62, and a liquid conducting cavity to accelerate the conduction of the liquid; the provision of the liquid conducting hole, the liquid conducting groove 62, or the liquid conducting cavity accelerates the conduction of the atomized liquid, reduces the conduction path of the liquid in the porous ceramic member 60, and can improve the permeability of some macromolecules in the e-liquid. Fig.21 As shown, this embodiment uses a liquid guide groove 62.

[0053] like Fig.19 As shown, a concave-convex portion 61 is provided on the top of the porous ceramic part 60, and the bottom of the liquid-conducting cotton 30 is embedded with the concave-convex portion 61. The embedding here refers to: the liquid-conducting cotton 30 is directly embedded in the concave-convex portion 61, or the bottom of the liquid-conducting cotton 30 is also provided with a concave-convex structure 31, and the concave-convex structure 31 is matched with the concave-convex portion 61, that is, the two are concave-convex matched. Specifically, the concave-convex portion 61 is at least one groove and / or at least one protrusion provided on the top surface of the porous ceramic part 60, and a concave-convex structure 31 is provided at the bottom of the liquid-conducting cotton 30. The concave-convex structure 31 of the liquid-conducting cotton 30 is embedded with the protrusion or groove on the top surface of the porous ceramic part 60. In this way, the contact area between the liquid-conducting cotton 30 and the porous ceramic part 60 can be increased, which is beneficial to optimizing the liquid conduction effect. At the same time, the thickness of the liquid-conducting cotton 30 and the porous ceramic part 60 can be adjusted according to actual needs to achieve the desired liquid conduction effect.

[0054] like Fig. 20 As shown, the liquid-conducting cotton 30 is further preferably provided with at least one of a liquid storage hole 32, a liquid storage tank, and a liquid storage cavity for storing liquid; wherein the liquid storage hole 32 is a through hole that passes through the top and bottom of the liquid-conducting cotton 30, the liquid storage tank refers to a trough body opened at the top of the liquid-conducting cotton 30, and the liquid storage cavity refers to a relatively closed cavity set inside the liquid-conducting cotton 30. The above structure allows more liquid storage space to exist in the liquid-conducting cotton 30, storing more atomized liquid to be quickly absorbed by the porous ceramic member 60 below, thereby ensuring that the supply of atomized liquid is relatively sufficient during continuous operation. This embodiment adopts a liquid storage hole 32.

[0055] Embodiment 2, as Figure 22-Figure 23 The electronic atomization device is shown, comprising an atomizer housing 100, in which the heating atomization core 200 of Example 1 is arranged, and a liquid storage chamber 300 is arranged between the atomizer housing 100 and the heating atomization core 200. When the electronic atomization device is working, the liquid storage chamber 300 stores atomized liquid, and the liquid storage chamber 300 guides liquid to the heating atomization core 200, and air enters the atomizer housing 100, and the air flows through the heating atomization core 200, and the heating atomization core 200 atomizes the atomized liquid to form atomized steam, and the air and the atomized steam are mixed to form an aerosol, and the aerosol flows out of the atomizer housing 100 and is finally inhaled by the user.

[0056] Other structures of the electronic atomization device can adopt existing technologies and will not be described in detail here.
